To all whom. it may concern:

5e it known that I, NATHANIEL Fnos'r, a citizen of 1h United States, and a resident of Bloomington, in the "county of McLean and State of Illinois, have invented a ncwand Improved Water-Closet, of which theiollowably in connection with an airtight tank, but whichv may be connected with any other form of tank. if desired, the valve being so arranged that the seating or v unscating thereof is not dependent upon springs as is usually the case, the only spring employed being an auxiliary medium or normally holding the seat ele- "vated ior ventilating purposes and when the water pressure is insufllciont, the principal medium to such 20. end, however, being the water pressure in the valve A nother purpose of the invcn tion is to provide a sanitary construction oi the bowl, which bowl is so an ranged at the rear as to form a 'cntilating chamber for carrying off offensive odors which are usually allowed '25 to escape into the room Another purpose of the invention is to provide a flushing valve which will be simple and positive in operation and economic and durable in construction, and

, one wherein the water pressure is utilized to normally 3O keep the valve closed, the valve being, opened automatically by the pressure exerted on the seat by the occupant thereof.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter 35 fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a vertical section through the improved closet and valve, the parts being in normal position;

Fig; 2 is an enlarged vertical section through the vnlve ol' the closet and adjacent portion of the bowl, showing the valve open d ior admission oi writer to the flushing "4,5 tank; Fig. 3 is ahorizontal section through the dev ce at the rear with a jet pipe 10, and the outlctll ol thepipe H) is at the-rear bottom portion of thcbowl proper. The bowl A is'providcd with a curved par this )ocket is provided with a rerun which extends downwardly and rearwardv from the front, and the said partition also extends from side to side of the bowl, its upper face being concrrved. The bottom 14 proper oi the bowl; extending from the rear to the front below the partition 12, forms a. chamber or channel 15 between. it and the partition 12; but the said channel 15 is open at its upper end, being connected directly with a discharge tube or channel 16 iormed integral with the bowl, by 'meansof a suitable outer member 13, extending from the upper portion of the partition 32 downward to 9. connection with the sewer or drain pipe.

A metal shield 17 is made to rest upon the upper edge 5f the bowl, and that portion of said shield which e);- tends at the sides and front of the bowl is curved downward and somewhat inward as shown in Fig. 1, so that when water is directed to t inner member of the said shield the Water will he forced to flow down the sides of the bowl and thus tend to wash it at such ooint. The shield l7 provided at its war with a n 3 horizontal flat extension 17, and the our coruinu ion '19 of the iorward and side sections 17 of rhcsuidsu' f-l closed at the bottom, as shown in Fig. 3, and is connected with a tubcorrhumlicrfll, which is formed-.1: th=- lower com ral portion of the llut upper OXl-Mlsinur IT or l ud shield, as is shown in Figs. 1 and at. This clnuntwr l0 errant.- out through the roar of the bowl, and is CulflILCilQtl a1 its rear portion with the upper end oi the pipe l0, us is shown in Figs. 1 and 2; and the outer end of. this chainbcr 20 is connected with a flushing valve B to be hereinafter described. The rear closed scclion l9 ol the shield 17 is provided with d uvnvnu'dlypxtending tubes 2i, so that the'walcr entering the chamber 20 and passing around the rim, a side and nirwurd porli on of the shield, in addition to passing down at the inn r sides oi the bowl will be directed downward as to effectually wash the roar inner wa l ol' lho bowl, as shown inligs. land 2'}. Thcscat 22 is of the usual con struclion, and is preferably secured to a skeleton metal frame 23. This frame has a hir -e connection. 24 u its rear usually with the said upper cxicnsion l7Fol' the shield 17 {or the bowl, as shown in 4X pin 25 extends down lrom the re oi the seat 222 or its supporting lizunc inFigs. l, 2 and 3; and this pin opw the flushing valve ll when the seat is occu )ied ice at such time ng or ilu. Figs. 1 and Loni or main casing 3b of thesaid llusl connects with the upper portion of the lower or main casing 28, and likewise with an upper chamber 34 pro vided preferably with a removable cover. This chamber 34 has asuitabl'e connection 35with a source of water supply.

Ayalve seat 36 is formed'ih the upper chamber 34 where it connects with, the intermediate member 33 of the flushing valve casing; and a second and lower valve seat 37'is provided where the said intermediate member 33 connects with the lower or main section 28 of the said valve casing, as is shown in Figs. 1 and 2.

The stem of a valve 38 slides freely inthe intermediate member'33 of the valve casing B, as also shown in Figs. 1 and 2, and said valve stem is provided with a lower head 39 adapted for engagement with the lower seat heretofore mentioned. Said lower head 39 of the valve likewise rests upon the horizontal member of the lever 32 connected with the plunger rod 27. A second and upper head 40 is secured to the stem of the said valve 38, and said upper head 40 is adapted for engagement with the upper sea't 36 in the upper chamber 34 oi the valve, and when one of the heads of the valve is seated the other is unseated. In the open position of the valve,. or that which permits water for flushing purposes to be introduced through the valve from a source of supply, the upper head 40 is unseated as shown in Fig. 2 and the lower head 39 is seated; at such time the water will flow through the.upper chamber 34 of the valve casing and its intermediate member 33 into a pipe 41 which is connected with the said intermediate member 33 of the valve casing at a point above the lower seat 37. This pipe 41 is connected with a flushing tank 42, said tank being preferably air-tight, although it.is not absolutely necessary that it should be so made. The open position of the valve is taken when the seat 22 of the closet is occupied, and the pin 25 carried by said seat forces the plunger rod 27 rearward thus causing the lever 32 to force the valve 38 upward, as is clearly shown in Fig. 2; and as soon as the seat is unoccupied the spring 29 acts to force the plunger rod inward or to its normal position, permitting the valve 38 to close, the actual closing of thevalve being brought about by the pressure of the in-coming water.

A vent box 43 is erected atthc rear of the closet, being preferably placed upon the shield extension 17 of the bowl shield 17; and said vent box is provided with a pipe 44 at its lower end, preferably oval in cross section.

This pipe'is connected with the extension 17' of the shield 3.7 at a suitable openihg therein as shown by dottpd lines in Fig. ,3, so that the inlet pipe 44 connecting with the vent box 43 is connected .with the bowl A at each side of the flushing chamber 20. Consequently the odors as the fiushing'operatio'n takes placeare forced upward into the vent box 48, and said vent box 431m a {Onnecuon heated-flue of j from the chamber of the said shield, 21' valve casing con- "neeted with the chambered portion of the flushing shield, I

In the detail operation of the closet, when the seal is occupied the valve 38 is forced upward so that its lower head is seated and its upper head isunscatod, where-'- upon the water entering the valve casing is forced up into the tank 42; but the moment the seat is relieved from pressure the valve seats itself at its upper head and unseats itseli at its lower head, and the water will immediately flow from the tank 42 into the lower portion of the valve casing and from thence into the jet pipe 10 and to all the outlets in the flushing shield.

The closet ispreferably made of enameled cast iron; but without departing from the spirit of the invention and with slight changes'in form, the closet may be. made of earthenware, in which event the jet pipe l0 will be made integral with the bowl.
